Background: Placental syndrome, mainly composed of preeclampsia and fetal growth restriction, has an impact on the health of mother and baby dyads. While impaired placentation is central to their pathophysiology, the underlying molecular mechanisms remain incompletely understood. This study investigates the association between placental syndrome and metabolic alterations in 1-deoxysphingolipids (1-deoxySLs) and polyamines, along with their regulatory enzymes.

This study aims to delineate the levels of Cd exposure in maternal blood, placenta, and cord blood, and to explore the association between Cd levels and the risk of preeclampsia (PE), as well as its potential impact on fetal growth among affected individuals. A case-control study was performed at the First Hospital of Shanxi Medical University, involving 373 pregnant women diagnosed with PE and 485 controls. Cd was measured in maternal blood, placenta, and cord blood using ICP-MS.

Background: COVID-19 infection during pregnancy could be associated with placental histopathological changes such as vascular diseases and malperfusion. There are studies showing that mRNA vaccines are not associated with significant placental pathological changes. Our objective was to evaluate the placental histopathology in pregnant women who received Sinopharm, an inactivated virus vaccine, during pregnancy.

Sulfasalazine is a non-specific immunomodulator with haemolytic anaemia as a known side effect that crosses the placenta. We present a preterm neonate with cardiac arrhythmia secondary to hyperkalaemia in the setting of maternal sulfasalazine therapy. A preterm infant was born to a mother taking hydroxychloroquine, sulfasalazine, aspirin and enoxaparin throughout pregnancy.

Fetal growth restriction (FGR) is characterized by the inability of the fetus to achieve its growth potential due to pathological factors, most commonly impaired placental trophoblast cell function. Currently, effective prevention and treatment methods of FGR are limited. We aimed to explore the pathogenesis of FGR and provide potential strategies for mitigating its occurrence.
